New Delhi: Amidst the internal turmoil in AAP, a party MLA has started a signature campaign seeking the expulsion of the father-son duo of Shanti and Prashant Bhushan along with Yogendra Yadav from its ranks.

The campaign is being undertaken by Kapil Mishra, the AAP MLA from Karawal Nagar, who said he has so far got a positive "response" from fellow party MLAs.

"I will give this petition, with the support of our MLAs, to Arvind (Kejriwal) ji once he comes back. I have spoken to all our MLAs and they have agreed to sign the petition," said Mishra, who also called for "exemplary action" against those found to be involved in anti-party activities.

Incidentally, the petition is also a replica of the charges levelled by AAP leaders on Tuesday. "During the Assembly polls, the party was fighting war on two fronts. On one side, we were fighting a war with outside forces (the Congress and BJP) and on the other side, we were fighting with our own people.

"They tried to malign the image of our party and our leadership," he added. Prashant and Yadav were voted out from the AAP's PAC last week in the wake of allegations by its members that they wanted to remove Kejriwal from the post of the party's National Convener.
